Suppose that 1212 of all cars sold at a Nissan dealer in a given year are Altimas, 1313 are Maximas, and the rest are Sentras. Suppose that 1212 of the Altimas, 1212 of the Maximas, and 2323 of the Sentras have a moon roof. Answer the following questions. For each question, first decide whether the probability is a conditional probability or not. 1. What is the probability a randomly selected car has a moon roof? 2. What is the probability that a randomly selected car has a moon roof given it is a Sentra?   3. What is the probability a randomly selected car is a Maxima if it has a moon roof?
